Frequently Asked Questions
Q1: What's the difference between 500 Da, 1000 Da, and 2000 Da?
The 500/1000/2000 Da (Daltons) difference reflects average molecular weight. Lower molecular weight (500-1000 Da) = higher bioavailability and faster absorption; 2000 Da = standard hydrolyzed collagen.
Q2: What's the difference between marine and bovine collagen?
Marine collagen is sourced from fish skin/scale (Type I, smaller peptides, faster absorption). Bovine collagen is sourced from cow hide/bone (Type I + III). Marine is preferred for pescatarian and Halal/Kosher markets.
Q3: Can Marine Collagen Peptides be combined with other ingredients?
Marine Collagen Peptides are commonly combined with Vitamin C, Hyaluronic Acid, Biotin, and Elastin in beauty-from-within formulations. We recommend consulting with your formulation team.
Q4: What's the regulatory status in the EU?
Marine Collagen is permitted as a food supplement ingredient in the EU. Allergen declaration (fish) is required on label. Specific regulatory status depends on intended application and labeling.
Q5: How is Protein Content measured?
Total Protein is quantified via Kjeldahl (N × 5.55 for collagen) or Dumas combustion method. Hydroxyproline is quantified via HPLC as the collagen-specific marker.
Q6: What's the typical MOQ?
Standard MOQ is 25 kg. Smaller quantities (5-10 kg) are available for evaluation.
Q7: Do you offer custom specifications?
Yes. Custom specifications (e.g., specific molecular weight, particle size, flavor masking) can be discussed with our coordination team.
Q8: What documentation is available?
Standard documentation includes COA, MSDS, allergen statement, Non-GMO statement. Additional documentation available upon request from production partners.
